The package is for the following paper:
    Cai, Yongyang, William Brock, and Anastasios Xepapadeas (2022).
    Climate Change Impact on Economic Growth: Regional Climate Policy under Cooperation and Noncooperation.
    JAERE, forthcoming.

The folders Case1 - Case6 contain the GAMS code SpatialDICE.gms and its associated damage coefficient 
file for each case 1-6. The folder "data_for_cases" contains the other input files for SpatialDICE.gms. The associated SSP1 popultion path is provided in RegionalPop_SSP1_Annual.csv, which is aggregated from Burke et al. (2018).

The folder "calibrate_climate_anomaly" contains the GAMS code and data for calibrating the carbon cycle 
and the regional temperature system. The four RCP scenarios and historical regional surface temperature anomalies and ocean temperature anomalies are aggregated from CMIP5. The RCP data are from MAGICC6.

The folder "calibrate_damEconGrowth" contains the GAMS codes for calibrating TFP in the North and Tropics/South without climate damage (Spatial_noDam_North.gms and Spatial_noDam_TS.gms), with ten-year lagged climate impact (Spatial_Dam_lag10_North.gms and Spatial_Dam_lag10_TS.gms), and with persistent climate impact (Spatial_Dam_growth_North.gms and Spatial_Dam_growth_TS.gms). The three GDP scenarios used for calibrating TFP are RegionalGDP-country-lag0-SSP1-rcp26b.csv, RegionalGDP-country-lag1-SSP1-rcp26b.csv, and RegionalGDP-country-lag5-SSP1-rcp26b.csv, which are aggregated from the countries' projected GDP of Burke et al. (2018). The calibrated TFP parameter values are input arguments of the GAMS codes.
